Want to upgrade to Win7 from XP Home Edition on old 32bit custom system. Applications: email, stock trading and charts, web surfing, streaming video. Also want to add backup external drive (Iomega 1T. eSATA 3Gb 34280. My mboard is an Abit IS7G, 4G 1066 RAM, dual 35G Raptors, SATA1.5, Core2 Duo 2.4, 450W Power Supply. Am considering replacing Raptors with WD 1T Green. Will Win7 upgrade cover all this? Do I need an eSATA PCI card? Can I go to 64? What do I need to run legacy XP programs? Thanks for info.
There are only two requirements for running a 64bit system. One, that the OS is 64bit. And two, that the CPU is capable of 64bit (which yours is). All you have to do is pop in the install CD and choose x64 this time around and that's it.
You don't need anything in order to run XP programs, but it's possible that a few you have just won't be compatible (since you're going to 64bit). I'm not too sure what you mean by "cover all this", but if you mean "Will the hardware still work 100% with the new 64bit system?", then yes, you'll be just fine.
